The "complete form" button at the bottom of the s2member form is not working or clickable. Not sure how or where the option is in the s2member section to maybe delete and add it again but not sure why it stopped working to begin with.

Specifically, I can't click the button that says "Yes, I want to receive updates via email" I can click "Submit" but the option for email info is not clickable. It looks glitchy when trying to click. Any ideas?

I have just taken a look the the whole page's code using View Page Source and can see that you have added that line as a custom Registration/Profile field. I suspect that it might work better if you moved it to somewhere before the Captcha section.
